Answer to Question 1

The density of a pure metal is a definite physical constant. An alloy will have a
slightly different density. A check on melting points will give further evidence.

Answer to Question 2

A brief answer the student might give is that the density of water is a function of the
mass of the water molecules and the spacing between them. The spacing is a function
of temperature and becomes a minimum at 3.8C.
